one of the things that screws up safety statistics is the fact that people routinely refuse to follow safety rules.
I work in heavy construction and probably 95% of the accidents, of which there are many, come from people cutting corners.
for example, JFK Jr. and his wife and sister in law are all counted as "private pilot deaths", but he literally committed "moron-cide."
He flew out over the ocean in sketchy weather, at nighttime, without an instrument rating. And he was kind a meathead, he was not a bright guy.
When he experienced fatal spatial disorientation and nosed his plane into the water at 300 mph, why does that get attributed to the sport of private flying? He didn't die of flying. The wings didn't come off the plane. The motor didn't quit. He literally died of arrogance and foolhardiness.
If someone with a 90 IQ reloads ammo in a foolish manner and none of the rounds will even fire, or one blows up the gun, that should not count against the safety of reloading.
That being said, I would never buy commercial reloads. Because I have no control over the reloading process.
And I would never shoot reloads where the powder charge wasn't being checked for each round. I used to use a powder checker die, but I never looked at the thing, just kept visually checking the load in the case, so I stopped using it.
